W. F. DIDEN POWER TRANSMISSION MEGHANQISM Filed June le. 1924 5 sheets-sheet 5 @ttor mi r a Cinne (ein LWWJEllt-TEAIFSMESSFN n emission mechanism., has particular reference to improved mechanism tor rotating the drive wheels ot automobiles or trnrhs so as to eliminate the luse ot common ditterential mechanisms now utilized. -While the invention is adapted tor various rises it is herewith particularly illustrated in conjunction with the ame and wheel oi a motor vehicle, the device being adapted to automatically clutch rotatable member' to a rotatedmemloer in either forward or hachmoveinent so long as the rotatable nirmher is desired to loe dri-ven, lout permitthe rotated nfiemher'to overrun under certain conditions, such as in making a turn n the case ot motor vehicles and the like.

rThe objects ot. the invention are, to generally improve devices ot this character, to simplify the construction thereof, to insure certain and positive operations, to reduce lost motion to provide'a structure which is reliahle, comparatively inexpensive to manufacture, durable, strong9 eiiicient and well adapted to the purpose Jfor which it is desired.

lll" th the ahove and numerous other ohjeets in view as will appear as the description progresses, the invention resides in certain novel t'eatures of construction, and in the comloination and arrangement ol'A parts as will he hereinafter more fully descrihed and claimed.

The present invention relates to a power .dogs used in conjunction with the inventio.d

.on the axle casing hy means of roller hearings 3 or in any other suitable manner. An annular tlange A projects outwardly trom the outer tace ot the wheel huh 2 and a plurality oi hey liars 5 are projected therefrom, losing fitted in grooves 6. A ring 'i' is provided with a plurality ot notches 8 `ler receiving the lrey hars 5 and on its interna-l 'race is provided with ratchet teeth 9. A ring il@ ot smaller diameter than the-ring '2 is post tioned within the contines ot the tlange t and the lrey hars 5.7 The axle casing ll is mounted over the axle 1 and it is within .this casing that the axle l is actually rotatahle.. This easing has keyed thereto afstar wheel or gear l2. A plurality ot dogs. 18 and la are pivoted to the ring 10.L Springs lfi hold these dogs normally in engagement with gear l2. These dogs i8 and Mare arranged 1n pairs and connected hy rods l5. Each Vrod is pivoted to 'one dog 18 oi? one pair outwardly ot the pivot 1li ot said dog and and springs 18 normally hold themiout ot engagement with the ratchet teeth @et the ring` A series ot pivoted arms 19 are mounted on the ring l@ tor engaging springs 20 whichare iixed at one endas at 22 to the ring 10 while the other ends are engaged with the dogs 17 so that these arms 197 may he swung to tension the s rings 20 tor over-- l coming the springs 18 an throwing the dogs 17 into engagement with the ratchetteeth il of the rings 71 'lhese arms 19 are somewhat in the l'orm ot cams as will loeclearly understood, hereinafter and will loe referred to trom now on as cam arms. f n

A plate 2li is mounted on, to rotate with,

litigare tl showing the parte in ditlerent n alla 'i inname the lugs 54E to drive the disk 28 and ring l() with the airle immediately atter the pins 25 release the dogs 13 and 14 from the gear 12,

yand the dogs 17' will therefore drive the ratchet ring 33 and the vehicle wheel to which the latter is keyed, the dogs 1'? being then released are linactive as shown in Figure 2. rllhe dogs 13 and 1t engage the star wheel or gear 12, which is lined to the stationary aide casing or housing 11, so as to hold the dislr' 28, ring 10 and associated parts stationary while the axle 1 and the plate 24,A with its pins 25, 26 yand 30 rotate so that said pins `26 or 30 may positively effect engagement ot the dogs 17 with the ratchet. ring 7 or the dogs 1'4" with the ratchet ring 33. ll-lowever, in order to prevent damageto the various parts, it is essential that the dogs 13 and 14 be released toj permit the disk 28 and ring` 10 to turn with the axle and plate 2li before the arms 56 engage the lugs 5t) or the lugs 54e drive said disk 23'and iing 10, and the pins 25 are accordingly disposed to effect release of the dogs 13 and 14 iinmediately prior to engagement oit said arms 56 with said lugs 50 or 54.

What l claim as new is: l

l. lin` combination, a driving member, a driven member, a clutch therebetween including a supporting member, a clutch controlling plate fixed to the driving member and 'capable of limited rotation relative to said supporting member of the clutch and having pins extended therefrom for controlling the movable clutch elements ot the clutch, a brake mechanism including astationai'y gear and dogs rotatable with the supporting member ot the clutch, some ot said pins ot the controlling member being enifgageable with the dogs to hold them out ot engagement ,f with the gear when othernpins thereof are 'actuating the clutch elements.
